Avid wide/ tall gear install from mark IV on c model

22 posts in this topic

I found some taller gear for my avid c model on barnstormers the owner had it on a mark IV and said it was made at the avid factory before they closed. I was hoping it would be a direct bolt on but the owner said it would need some welding of a gusset in the center. Is anyone familiar with this gear and the gusset he was referring to.

Enclosed are pictures of the gear

Thanks

I believe usually the cabane is bolted in place with the front landing gear bolts. I do think that if the center of the cabane was fastened to the seat truss, it would make for a stronger set up. Haven't seen any other Kitfoxes or Avids done that way though. JImChuk

Looks to me like he just cut the tops of the cabane vee off instead of unbolting it from the plane. You will have to fab a new mount for the tops. If I were you, I would make a bar that went all the way across on the top of the vee and then put your tabs onto that to bolt into the front fixture. This gives you additional strength when / if they ever bottom out.

I think that the further down the center of the cabane is from the bottom of the plane, the less leverage is there to try to pull the sides of the plane toward each other. There have been pictures posted of that happening, with the bottom tube of the seat truss being buckled inward. Of course if you lower the cabane, the arms with the bungees on them will need to be shortened as well so the wheels aren't splayed out. JImChuk

I have read all I can find on all this and still feel very uneducated and confused. Everyone has a different answer on what works or should work very much like the correct amount of toe in or toe out. I found the thread that showed pops dory's now machine as well as some others.

Toe in will tend to steer into the turn/ground loop, toe out wants to steer it out. At least that's what I've always thought. JImChuk

Weight is on the groundloop wheel - You may be right about toe-in? (Too much deep-thinking for my Chemo brain right now!) Either way, looks like straight - no toe, would be best? I have no real experience with full groundloops - that's why I went Nosedragger when legs got unstable! EDMO
